`J OURNAL-BOX.

SPECIFICATION forming p'art of Letters Patent No. 239,290, dated March 22, 1881. Application tiled January 31, 1881. (No model.)

To all 'whom it may concern Be it known that I, ALVA WORDEN, of Ypsilanti, in the county of Washtenaw and State of Michigan, have invented an Improvementin Journal-Boxes, of which the following is a specication.

The nature of my invention relates to certain new and useful improvements in the construction of that class of journals which are designed to run in one direction and their boxes adapted to prevent such journals from rotating except in the desired direction.

My inventionconsists in the peculiar con- .struction of the journal-box, carrying within itself an independent pawl, which is designed to so engage with the radial ratchet-teeth of the shaft as to allow a free rotation thereof' in one direction, while it will absolutely prevent its rotation in the opposite direction.

Figure l is a plan view of my improved box with a section of shaft therein. Fig. 2 is a perspective view of the shaft detached, and showing the ratchet-teeth. Fig.3 is a detached view of the independent pawl. Fig. 4 is a vertical section on line x x. Fig. 5 is a vertical section on line y y.

In the accompanying drawings, which form a part of this specication, A represents a journal-box, which for small boxes may be cast whole, and for larger boxes may be cast in. two parts and bored out in the usual manner. The inner face of this box is provided with a centrallylocated recess, a, and with a hole, Ig, through the wall of the box, from near the center of this recess; or, if preferred, this recess may be annular for ease of manufacture or casting.

B is a concave-faced pawl, provided with a stem, c, projecting from :its rear face and near one end. This stem, when the pawl is in place within the recess, projects through the hole b. When the pawl is in place and not iu operation it simply fills that portion of the recess in which it is situated. j

C is a shaft, with its periphery pro vided with ratchet-teeth d. W'hen the parts are together the shaft will rotate in one direction but when an attempt is made to rotate it in an opposite direction the overweighted end of the pawl will engage with one of the ratchet-teeth and prevent it. V

This box and ratcheted shaft will be found useful for chain-pumps, windlasses, sewingmachines, door and gate springs, and in other places too numerous to mention.

What I claim as my invention is l. The combination, with a journal-box', A, provided with a central recess, a, and hole b, extending through the wall of the box, of the pawl B, provided with a stem, c, projecting from its back and inserted in the hole in the box, substantially as described.

2. The combination, with the shaft C, having ratchet-teeth d near one end, of the journalbox A, provided with a recess, a, and pawl B, substantially as described, and for the purpose set forth.

ALVA WORDEN.
